As described above, in the control system that food processing assembly line, semiconductor production line etc. are connected by multiple PLC 1 and are constituted
In system, each PLC 1 obtains control data from the PLC 1 of the previous process in multiple processes.Each PLC 1 is based on acquired timing
Data in the control data of property, corresponding with the product for being currently at this process, control the manufacturing device 3 of this process
System.
Herein, to newly starting food processing assembly line corresponding with existing food processing assembly line shown in Fig. 4
The case where be illustrated.In the user of control system, it is desirable to by production line identical with the existing production line with actual achievement
There are many people also introduced to other factories.At this point, user wishes sometimes before the PLC 1 for constituting the production line newly set is all complete
Prestige successively executes confirming operation from the PLC 1 accessed.
But when production line newly starts, it is uncommon that the whole PLC 1 for constituting production line, which obtain access in the phase same time,
's.For example, being set in the food processing assembly line newly set as corresponding with kneading-separation procedure PLC 1b of Fig. 4
It is standby, access PLC 1B shown in Fig. 1 (b).But in the food processing assembly line newly set, as metering-throwing with Fig. 4
Enter-corresponding the equipment of PLC 1a of mixed processes, PLC 1A shown in Fig. 1 (b) is not accessed also.
Herein, kneading-separation procedure PLC 1B is based on previous process, that is, metering-investment-mixed processes PLC 1A
Control data, manufacturing device 3B is controlled.But the PLC 1A of previous process is not yet accessed.Therefore, PLC 1B can not
Control data are obtained via the input unit 15B of output unit 13A and the PLC 1B of PLC 1A from the PLC 1A of previous process.
In addition, the PLC 1B in the production line newly set leads to as described above, not with the PLC 1 etc. in existing production line
Signal wire etc. is crossed electrically or online to connect.Therefore, it is impossible to control data from the equal acquirements of the PLC 1 of existing production line.
Therefore, before each PLC 1 for constituting the food processing assembly line newly set is all complete, even if wanting from having accessed
PLC 1B rises and successively executes confirming operation, Fault analytical, and PLC 1B can not also be held before the PLC 1A access of its previous process
Row confirming operation etc..
Therefore, it for the control system of embodiment 1, carries out in the food processing assembly line of Xiang Xinshe in application, setting
Set the log recording data reproducing device 5 that log record file is obtained from exterior storage medium 4b.The PLC 1B of subsequent handling from
Log recording data reproducing device 5 is obtained via log record file by previous process i.e. metering-investment-mixed processes
Control data acquired by PLC 1a.The PLC 1B of subsequent handling is right based on the control data obtained via log record file
The movement of manufacturing device 3B is controlled, therefore even if PLC 1A without previous process, is also able to carry out and is considered previous work
Confirming operation etc. after the data of sequence.In addition, by the control system of embodiment 1 in semiconductor production line the case where
Under, it is also identical as the case where being applied to food processing assembly line.
Fig. 6 is the flow chart for indicating the motion flow of the log recording data reproducing device in embodiment 1.Using Fig. 6,
The movement of log recording data reproducing device 5 in embodiment 1 is illustrated.
Firstly, user operates setting with terminal 6b before the movement of log recording data reproducing device 5 starts,
The control period of output object data and PLC 1B is specified.Object data configuration part 531 is exported to be based on from setting with eventually
The signal that end 6b is received sets output object data.Control cycle set portion 532 is based on connecing from setting with terminal 6b
The signal received sets the control period of PLC 1B.
In addition, installing the exterior storage medium 4b for being stored with log record file in log recording data reproducing device 5.It should
Log record file is the file for generating, storing the control data of manufacturing device 3a by PLC 1a.The control data are by PLC
The data for the timing that the data record unit 12a of 1a is collected into as unit of the log recording period.
In addition, log recording data reproducing device 5 is not limited to start to act when being mounted with exterior storage medium 4b,
It can be the reception movement sign under preassembled state and start to act.
In step s in fig. 6, file acquisition unit 54 reads in output object data from output object data configuration part 531
Set information.File acquisition unit 54 obtains log record file from exterior storage medium 4b, reads in the control number of manufacturing device 3a
According to.At this point, file acquisition unit 54 reads in control number in the control data of manufacturing device 3a, being set out by output object data
According to.
In step s 2, the setting in the control period of PLC 1B is read in data reproduction portion 55 from control cycle set portion 532
Information.In addition, control data are transmitted from file acquisition unit 54 to data reproduction portion 55.
In step s3, data reproduction portion 55 is by the control period of the PLC 1B as set by control cycle set portion 532
It is compared with the log recording period of the log record file as acquired by file acquisition unit 54, whether the two is unanimously carried out
Determine.
In the case where being different the period in the control period of PLC 1B and log recording period, it is transferred to step S4.In
In step S4, data reproduction portion 55 carries out interpolation to data, so that the control in the period of acquired control data and PLC 1B
Period processed is consistent.
Herein, the interpolation of control data is illustrated.Fig. 7 is the situation shorter than the log recording period to the control period
Under data the example that is illustrated of interpolation process.Fig. 8 is longer than the log recording period to the control period, is log recording week
The example that the interpolation process of data in the case where the multiple of phase is illustrated.Fig. 9 is to the control period than the log recording period
The example that the interpolation process of data in the case where multiple that is long, not being the log recording period is illustrated.Using Fig. 7,8 and 9,
The interpolation process of control data in embodiment 1 is illustrated.
Firstly, the interpolation process of the data in the case where shorter than the log recording period to the control period of PLC 1B is said
It is bright.For example, the control period is 1ms as shown in fig. 7, being set as the log recording period is 2ms.In this case, control data are as schemed
It shown in 7 (a), is collected as unit of log recording period 2ms.
But due to control the period it is shorter than the log recording period, control the period in it is any at the time of, sometimes not
There are corresponding control data.For example, in Fig. 7 (a), control data a1, control data a2 and the interval point for controlling data a3
It is not 2ms.But there is no control data between control data a1 and control data a2.Therefore, required control data
Lazy weight, in general, PLC 1B is not available these control data.
Therefore, data reproduction portion 55 carries out data using common data interpolation method based on acquired control data
Interpolation.Specifically, in Fig. 7 (b), data reproduction portion 55 is using common data interpolation method to by each control data link
Insertion packing A1 is calculated, and interpolation goes out each control data.In addition, common data interpolation method refers to such as linear interpolation, batten
Interpolation etc..These are usual ways, therefore the description thereof will be omitted herein.
In Fig. 7 (c), data reproduction portion 55 is obtained as unit of controlling period i.e. 1ms according to calculated insertion packing A1
Control data.For example, data reproduction portion 55 obtains between control data a1 and control data a2 according to calculated insertion packing A1
Control data a4.Just it is during control data a1 is until controlling data a4, from control data a4 to control data a2
For during only, the period is respectively 1ms.Data reproduction portion 55 obtains control data a1, control data a4 and control data a2
Deng as the control data after the control period with PLC 1B matchingly interpolation.
Next, be the multiple in log recording period the case where longer than the log recording period to the control period of PLC 1B
Under the interpolation processes of data be illustrated.For example, as shown in figure 8, being set as the log recording period is 2ms, the control period is
4ms.It in this case, shown in control data such as Fig. 8 (a), is collected as unit of log recording period 2ms.In addition,
In fig. 8, further it is shown that by the real data B1 of the value connection of each control data.
But due to controlling times that the period is longer than the log recording period, PLC 1B control period is the log recording period
Number, thus while in the presence of control data corresponding with each control period, but there are the unwanted controls of the control of PLC 1B institute
Data processed.For example, control data b1 and the interval for controlling data b3 are 4ms in Fig. 8 (a).Therefore, the control number between
It is the unwanted data of control institute of PLC 1B according to b2.
Therefore, data reproduction portion 55 removes unwanted data from acquired control data, and obtains remaining
Control data.For example, data reproduction portion 55 removes unwanted control data b2 from acquired control data in Fig. 8 (b)
It removes.Data reproduction portion 55 obtains remaining control data b1, control data b3 etc., matches as the control period with PLC 1B
Control data after ground interpolation.
Next, the feelings of multiple that is longer than the log recording period to the control period of PLC 1B, not being the log recording period
The interpolation process of data under condition is illustrated.For example, as shown in figure 9, being set as the log recording period is 2ms, the control period is
5ms.It in this case, shown in control data such as Fig. 9 (a), is collected as unit of log recording period 2ms.
But since the control period is longer than the log recording period, is not the multiple in log recording period, in control week
At the time of interim any, corresponding control data are not present sometimes.For example, in Fig. 9 (a), control data c1, control data
C2, the interval for controlling data c3, control data c4, control data c5 and control data c6 are 2ms respectively.But in control number
According between c3 and control data c4, there is no control data, therefore there is no the control numbers that the interval with control data c1 is 5ms
According to.Therefore, the lazy weight of required control data, in general, PLC 1B is not available these control data.
Therefore, data reproduction portion 55 carries out data using common data interpolation method based on acquired control data
Interpolation.Specifically, in Fig. 9 (b), the case where data reproduction portion 55 and Fig. 7 in the same manner as, use common data interpolation method pair
The insertion packing C1 of each control data link is calculated, interpolation goes out each control data.
In Fig. 9 (c), data reproduction portion 55 is obtained as unit of controlling period i.e. 5ms according to calculated insertion packing C1
Control data.For example, data reproduction portion 55 obtains the control data c3 in Fig. 9 (b) and control according to calculated insertion packing C1
Control data c7 between data c4.With regard to from control data c1 until controlling data c7 during for, period 5ms.Number
Control data c1, control data c7 and control data c6 etc. are obtained according to reproducing unit 55, as the control period phase with PLC 1B
With the control data after ground interpolation.
It is the explanation of the interpolation process of the control data in embodiment 1 above.
It is back to Fig. 6, in step s 4, data reproduction portion 55 is in the control period with PLC 1B matchingly to control number
After carrying out interpolation, it is transferred to step S5.
On the other hand, in step s3, in the feelings that the control period in log recording period and PLC 1B is the identical period
Under condition, it is transferred to step S5.In this case, interpolation of the data reproduction portion 55 without acquired control data.
In step s 4, data reproduction portion 55 exports acquired control data to PLC 1B.It is log recording above
The explanation of the motion flow of data reproducing device 5.
